Participants

Reaction Steps

70 g (0.19 mol) of the above synthesized 1,1-bis(4-methoxyphenyl)-1-(4-nitro-phenyl)ethane, 200 ml of tetrahydrofuran and 3.5 g of palladium carbon were placed in an Erlenmeyer flask, and the 1,1-bis(4-methoxyphenyl)-1-(4-nitro-phenyl)ethane was reduced by 13.65 l of hydrogen. After this reduction reaction, the tetrahydrofuran was distilled away from the reaction mixture under reduced pressure, whereby 1,1-bis(4-methoxyphenyl)-1-(4-amino-phenyl)ethane was obtained in the form of a white solid in a yield of 64.2 g.
